This value is expressed in hours and represents the number of hours before the lamp is at half its original brightness.

The lamp's success rate is based on a bell curve, so that a majority of (but not all) lamps will meet the lamp life hours specified.
-- Carl, Boston, Massachusetts. Carl, it depends on your definition of very long.. But generally speaking, a LCD projector lamp should last between 2,000 and 3,000 hours of viewing. That holds true for a Home Theater lamp or a lamp for a DLP TV. Of course, that number can vary. Like any kind of bulb, it might go dead in fewer hours than that, or it could last even longer. But if you buy a brand-name bulb that's compatible with your projector, you should get at least 2,000 hours of viewing. Now, how long is that in real-time? To use myself as an example, I've had a Sony VW60 Home Theater Projector, which has a Sony VW60 bulb, for about four years and I watch it quite a bit. I've used my projector for more than 1,700 hours and I have not had to replace the bulb yet.
